Prerequisites: Knowledge of any Modeling software, knowledge of coordinate systems and

Geometric transformations etc.

Course objectives:

The course is intended to provide basic understanding of Modeling and Analysis techniques


To acquire basic understanding of Modeling and Analysis software

To understand the different kinds of analysis and apply the basic principles to find out the stress

and other related parameters of bars, beams loaded with loading conditions.

To lean to apply the basic principles to carry out dynamic analysis to know the natural frequency

of different kind of beams.

PART – A

Study of a FEA package and modeling and stress analysis of:

1. Bars of constant cross section area, tapered cross section area and stepped bar

2. Trusses – (Minimum 2 exercises of different types)

3. Beams – Simply supported, cantilever, beams with point load , UDL, beams with varying

load etc (Minimum 6 exercises different nature)

4. Stress analysis of a rectangular plate with a circular hole

PART - B

1) Thermal Analysis – 1D & 2D problem with conduction and convection boundary

conditions (Minimum 4 exercises of different types )

2) Dynamic Analysis to find

2

a) Fixed – fixed beam for natural frequency determination

b) Bar subjected to forcing function

c) Fixed – fixed beam subjected to forcing function

PART – C (only for demo and oral exam)

1) Demonstrate the use of graphics standards ( IGES, STEP etc ) to import the model from

modeler to solver

2) Demonstrate one example of contact analysis to learn the procedure to carry out contact

analysis.

3) Demonstrate at least two different type of example to model and analyze bars or plates

made from composite material

Course Outcomes: At the end of the course the students are able to:

Demonstrate the basic features of an analysis package.

Use the modern tools to formulate the problem, and able to create geometry, descritize, apply

boundary condition to solve problems of bars, truss, beams, plate to find stress with different-

loading conditions.

Demonstrate the deflection of beams subjected to point, uniformly distributed and varying loads

further to use the available results to draw shear force and bending moment diagrams.

Analyze the given problem by applying basic principle to solve and demonstrate 1D and 2D heat

transfer with conduction and convection boundary conditions.

Carry out dynamic analysis and finding natural frequencies for various boundary conditions and

also analyze with forcing function.
